Table 3. Efficacy results: responder rates (MCID) at 6-month FU for bilaterally treated patients (all patients).

MCID responder rates at 6-month FU	n/N	Percent
6MWD responder (≥26 m)	12/20	60.0
SGRQ responder (≥4 points)	20/23	87.0
SGRQ responder (≥8 points)	14/23	60.9
RV responder (≥0.35 L)	19/25	76.0
FEV1 responder (≥10%)	16/28	57.0
Two or more MCIDs responder^	21/29	72.4

^, at least two MCID responses among 6MWD, SGRQ (4 points), FEV1 and RV; missing values have been counted as non-response. 6MWD, 6-minute walk distance; FEV1, forced expiratory volume in 1 second; FU, follow-up; MCID, minimal clinically important difference; RV, residual volume; SGRQ, St. George Respiratory Questionnaire.
